Solis S6 125kW 3 Phase Hybrid Inverter with DC - 10 MPPT for HV Batteries (WIFI/LAN)

Build robust, high-yield C&I solar + storage systems with the Solis S6 125kW 3-Phase Hybrid Inverter (10 MPPT)—designed to handle complex PV arrays, integrate high-voltage batteries, and maintain continuity for critical loads when grid conditions aren’t ideal.

Flexible PV design (10 MPPT / 20 strings)

The 125kW model gives installers real freedom on larger rooftops and multi-aspect arrays, with 10 MPPTs and up to 20 strings, 1000V max DC, and an MPPT operating window of 150–950V. With a maximum string input current of 21A, it remains compatible with today’s high-power modules—helping you maximise kWh yield without forcing awkward string compromises.

Oversize the PV for stronger returns

You can design with up to 250kW recommended PV array size on the 125kW inverter (up to 2× rated PV input highlighted in the datasheet) to drive better utilisation through more of the day—particularly useful on sites where export is constrained and self-consumption or charging windows matter.

HV battery integration built for scale

For commercial storage, the inverter supports Li-ion HV batteries (300–950V) and provides two independent battery ports for flexible layouts and easier future expansion. Charge/discharge capability is 100A per port (100A × 2 total), with comms via CAN / RS485, supporting scalable battery architectures and streamlined controls integration.

Reliable backup and heavy-load starting

Where resilience is part of the brief, the system achieves on/off-grid transitions in <10ms. In off-grid mode, the 125kW model supports up to 1.4× rated power for 10 seconds and 1.6× for 200ms, helping ride through motor starts and short inrush events without nuisance dropouts.

Designed for weak grids, gensets and complex sites

This range is positioned for challenging supply scenarios, with support for genset-hybrid operation and a three-in-one interface for integrating on-grid PV, wind power, and diesel generators. It also supports functions like demand management and anti-reverse flow, plus dynamic reactive power compensation to improve site power factor and reduce reactive power charges.

Monitoring and commissioning made easy (WiFi/LAN + SolisCloud)

Commissioning and ongoing service are simplified with a 7" LCD display plus Bluetooth + app, and integrated connectivity: WiFi + LAN + Bluetooth as standard, with optional 4G. Combined with SolisCloud remote monitoring and troubleshooting, installers can reduce callouts and support multi-site customers more efficiently.

Commercial durability

Built for demanding environments, it features IP66 ingress protection, -25°C to +60°C operating range, transformerless topology, and intelligent redundant fan cooling. Efficiency is strong too: up to 97.5% max, with 97.2% EU efficiency listed for the 125kW model.
